ADC — Cucumis sativus

Summary

CSA_2G252050, designated ADC, encodes an arginine decarboxylase (EC 4.1.1.19) in cucumber (Cucumis sativus) chromosome 2. The enzyme possesses a PLP-binding barrel domain and is localised to the cytosol and nucleus. ADC is associated with polyamine, putrescine, spermidine, arginine, abscisic acid, ethylene, nicotine, alkaloid and carbohydrate metabolism, the GABA shunt, fermentation, virus-induced PTGS, appressorium formation, and salt response. The gene has been linked to photosynthetic traits including net photosynthetic rate, quantum yield, transpiration rate, stomatal resistance and photochemical quenching, as well as nitrogen and proline content. Phenotypic associations include salt tolerance, iron deficiency tolerance, bacterial disease resistance, cold tolerance, seed germination, root and leaf development, plant height, flowering time, and responses to wounding, osmotic stress, salicylic acid and jasmonic acid. Studies of related genes in other species link the ADC family to drought tolerance, freezing tolerance, polyamine content and root architecture.
